Judge Nigel Seed QC, sitting directly behind Majumder, spotted his clerk viewing what looked like cartoon images of farmyard animals but could not make out if the content was sexual.

Later, he was shocked to find a list of pornographic websites on Majumder’s computer and decided enough was enough.

Majumder, of Burgoyne Road, Harringay, who had been working for the courts service for 27 years, later confessed to routinely watching internet porn when he was bored.

“I only looked at porn because the case was boring and did so once or twice a week since December 2009,” he told detectives.

Police then found indecent pseudo-images of children and extreme porn on his home computer.

Kingston Crown Court heard the married father-of-one made a series of porn searches during the rape trial on December 9 and 10, 2010. He also looked at non-sexual material with no relevance to his work.

Sentencing Majumder on Friday to seven months in prison, suspended for two years, Judge Nicholas Price QC said: “I’m told by your counsel that you didn’t think anyone could see what you were doing - you were wrong. The learned judge conducting the trial saw very clearly what you did.

“It’s incomprehensible that a man of your age and experience should behave in such an appalling way. It is inexcusable and reprehensible and you have no-one to blame but yourself.

“The very fact there are no comparable cases shows how rare, if not unique your case must be.

“You have lost almost everything including your job, your good name and the probable consequences are you will find it almost impossible to find another form of employment.
